What is monzonite rocks?
monzonite, intrusive igneous rock that contains abundant and approximately equal amounts of plagioclase and potash feldspar; it also contains subordinate amounts of biotite and hornblende, and sometimes minor quantities of orthopyroxene.
Is monzonite plutonic or volcanic?
Monzonite is a plutonic igneous rock intermediate in composition between syenite and diorite. Monzonite contains less quartz and more plagioclase than granite. Latite or trachyandesite are the approximate volcanic equivalents of monzonite.
What kind of rock is quartz monzonite?
intrusive igneous rock
quartz monzonite, also called adamellite, intrusive igneous rock (solidified from a liquid state) that contains plagioclase feldspar, orthoclase feldspar, and quartz. It is abundant in the large batholiths (great masses of igneous rocks mostly deep below the surface) of the world’s mountain belts.
Is monzonite mafic or felsic?
Quartz monzonite or adamellite is an intrusive, felsic, igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars.
What is monzonite made from?
Monzonite is an intermediate igneous intrusive rock composed of approximately equal amounts of K–feldspars and Na–plagioclase with minor amount of quartz (<5%) and ferromagnesian minerals (hornblende, biotite and pyroxene).
What is the volcanic equivalent of monzonite?
The volcanic equivalent of monzonite is latite. The plagioclase in monzonite is sodium-rich, ranging from oligoclase to andesine, and is moderately well shaped (subhedral to euhedral).
What is monzonite used for?
The rock seldom hosts gold and silver deposits, uses as building stone for monuments (The Mormon temple, Salt Lake City, Utah), and aids in mountaineering.
Is monzonite a type of granite?
Quartz monzonite is a rock similar to granite in general character and appearance but different in mineralogical and chemical composition. The chief basis for distinction, in brief, is the type of feldspar.
